Remote Low-Voltage Centralized Power Meter Reading Solution

There are two main remote low-voltage centralized meter reading solutions, one is the RS485 wired centralized meter reading solution, and the other is the power carrier meter reading solution. Let's talk about these two low-voltage centralized meter reading solutions.

◆RS-485 centralized power meter reading solution: Usually, the meters we buy are equipped with RS485 communication ports, so it is relatively cheap for hardware cost, and there is no need for built-in communication modules in the meters. The system adopts RS485 dedicated line communication, with fast meter reading speed and reliable communication, which can ensure 24h real-time communication every day, which is the most stable and reliable system at present. The system adopts the integrated RS485 meter, the meter has high measurement accuracy, and can directly read the stored electric energy data of the electric meter during communication, avoiding the secondary measurement of electric energy.

◆Power carrier centralized power meter reading scheme: The power carrier meter reading scheme does not need to re-setup the network, mainly relying on the wire to spread the data, the transmission is stable, the transmission is fast, and the installation is relatively simple, and the on-site construction is convenient. Some electricians are reluctant to accept the RS485 list because the on-site construction is too troublesome, even if the price is not very cheap, the carrier power line is directly transmitted, reducing the construction cost. The transfer speed is fast, relative to other wireless technologies, the transfer rate is fast.
